Is the above video a reasonably accurate portrayal of a Catalina 380?

There seem to be several available at reasonable prices on Yacht World. For a boat of this size is Yacht World the best place to search for boats?

Catalina boats appear to have a reputation for being a sturdy boat, easy to maintain, with easy availability of parts. Is this reputation deserved?

My only serious concern is the size of the fuel tank. Can an additional fuel tank be easily added? For long cruises I was thinking of a fuel bladder. Would a fuel bladder be problematic due to its weight?

The sailboat calculations appear reasonable: (1) capsize screening 1.85, (2) comfort ratio 30.24, and (3) sail area/displacement 16.31. The S.A./D ratio is not as good as other boats such as Beneateau, but is this a serious concern in light air?

I will be singlehanding and will eventually go on a circumnavigation. Of the production boats would a Catalina 380 (about 20 years old) be a reasonable choice or am I missing something?
